Cool plane and a nice build! Was that an actual concept from MiG, or something you or someone else came up with? Looks awesome!

Not entirely sure. Supposedly an unrealized MiG concept. I added the canards cuz I just like a good delta/canard. MiG has experimented with Canards on their MiG-35 and used them on the MiG-1.44 Flatpack which mine appears to be somewhat similar to.
